This happened in 2017. I was able to trace this video back to the city of Petrópolis, Rio de Janeiro, Brazil. The woman would survive the incident.
Translated fragments from news about the incident:
“A video recorded by a witness shows the moment when the ex-boyfriend pulls out a switchblade from his bag and strikes the 32 year old woman’s neck. This happened on a street in the Mosela neighborhood, in Petrópolis, Rio, on this monday (18th). According to police, the victim was also struck in the face.”
“He was arrested on scene and will be charged with attempted femicide. The motivation for the crime was, according to him, the end of the relationship.”
“The victim was taken to the hospital. They informed G1 that ‘the patient is hospitalized in the Intensive Care Unit (ICU), and has been stabilized.”
